If this is the effect your after use mulit replicate. (Edit/muti-replicate) 1.First model your first step. 2.Select the step. 3.Click on Edit, then Step. 4.Enter the values for the ofsets you want. In my example I use a z and y value slightly less than the dimentions of the step and 0 for x. Make sure the x y z size values are set at 100% and zero for the rotate, unless you want spiral stairs. theFOG
